|Abstract||目的：通过了解兰州地区2013-2014年度轮状病毒、杯状病毒、腺病毒、星状病毒等引起婴幼儿病毒性腹泻常见病 原体的流行病 学特点，对病毒性腹泻的预防和控制提供数据支持和理论依据。
|Other Abstract||Objective：To analyze the features of epidemiology and clinical characteristics of Group A Rotavirus (GARV), Human Calicivirus (HuCV), Human Adenovirus (HAdV) and Human Astrovirus (HAstV) in Lanzhou area of China from 2013 to 2014, and to provide data support and theoretical basis for the prevention and control of viral diarrhea.
Methods：A total of 232 stool samples were collected from hospitalized children less than five years with acute infection diarrhea, in Department of Pediatrics, the First Hospital of Lanzhou University, between July 2013 and June 2014. At same time, personal information and clinical data of those children were collected. Group A rotavirus was identified by enzyme-linked immunosorbent assay (ELISA), while G and P serotypes were identified by nested reverse transcription PCR method. Norovirus was confirmed by reverse transcription PCR method and Adenovirus by PCR method. Sapovirus and Astrovirus were detected by real-time quantitative reverse transcription PCR method.
Results：Among the 232 samples, 146 samples were detected with virus infection, with a rate of 62.93%, indicating that the virus infection was the primary cause for diarrhea among the infants in Lanzhou area this year. The infection rate of Rotavirus was 40.09% (93/232), which was the most prevalent one among the four viruses, then followed by Calicivirus （41/232，17.67%）. The detection rate of Adenovirus and Astrovirus were 7.33% and 6.03% respectively. There were 18 co-infections(7.76%) to be found while most of which were Rotavirus mixing with other viruses.
Conclusion：Rotavirus was the main pathogen for diarrhea in infants in Lanzhou area. The main epidemic strain GII.4 of Norovirus this year showed homology with the variant strain GII.4/Sydney2012 reported in Sydney in 2012.|
